For this task I configured R5 to assign an IP address to R4 via IPCP and I configured RIP on R4 to not verify the update-source.

As far as I can tell, it's in within the guidlines for the task.

I just finished the lab so I'm waiting to see how it's marked.

I can't make any sense of it.

Sun, 18 Mar 2012 11:59:57 +0000CCIE Routing & Switching Mock Lab 4Ricardo.Simba19202@/discussionsThis task also states that "Ensure that R1 can ping R2 across the Frame Relay Cloud" and restricting the use of a single frame-relay map on each spoke and not use inverse-arp. I don't totally agree with this task and its solution, is there any other way that spokes can ping each others even with these restrictions?]]>
Poor experience of Mock Lab 4https://ieoc.com/discussion/21170/poor-experience-of-mock-lab-4
Sun, 25 Mar 2012 21:30:59 +0000CCIE Routing & Switching Mock Lab 4terrychow21170@/discussionsHi all,

I have tried the Mock Lab 4 yesterday at 12:00PM (HK Time GMT +8), after finished the Troubleshooting lab, I have go out for lunch.

After 30 mins lunch break, when I back to my computer, the Mock Lab shown "All Done" and the solution guide came out.

Which means that my lab is finished and I cannot do my configuration lab. This is very poor and I lost a chance to test myself. I submit a ticket to INE but no reply until now.

Best Regards,

Terry Chow

Task 5.1 - Why do we need to redistribute BGP into IGPhttps://ieoc.com/discussion/5045/task-5-1-why-do-we-need-to-redistribute-bgp-into-igp
Tue, 03 Feb 2009 19:42:38 +0000CCIE Routing & Switching Mock Lab 4Sesano Dream5045@/discussionsI did this Mock Lab recently but when I got back my report, I missed this task because the proctor said "BGP prefixes are not redistributed into IGP"

I really don't know why we need to do this.

Basically we're running BGP on R1, R4 and R6 and all of them are AS 100 with R1 configured as Route-Reflector to both R4 & R6.

R4 has an eBGP peering with BB3 and R6 has an eBGP peering with BB1. Both BB1 & BB3 are both in AS 54. All routers has reachability to the prefixes from AS54, so why do we need to redistribute BGP into IGP.

Whoever has done this lab in the past or experts from IE should be kind enough to comment on this task !

- The IGP topology map has mixed G0/0 and G0/1 up on R6. It is correct on the other topology map.

- In question 6.1 we are asked to configure PIM on SW2 F0/4 and F0/5. This does not make sense since it needs to be configured on Vlan42 and Vlan52 in order for R5 and R4 to get any connectivity. The interface F0/5 does not even connect to any router.

- Task 4.12 we are asked to make sure that 145.X.45.0/24 should have metric of 2. And then that all other rip routes should have a metric of 10. Its not clear in my opinion that its only the RIP routes on R6 that should have a metric of 10. It would have been nice with a task that would have told us “All other RIP routes on R6 should have a metric of 10.”

- In task 10.1 I believe I provided a correct solution (will see when it gets graded) but the router on your lab rental did not have enough memory to run the IOS provided so got some nasty core dump when I tried to reload.

In the Solution guide there are several issues that are very confusing:

- Task 1.6 does not exist in the Mock lab but the solution guide shows a port-security configuration.

- Task 4.6 you show a solution with a tunnel with a new IP address configured. The Lab Do’s and Don’t dictate that “Do not change or add any IP addresses from the initial configuration unless otherwise specified.”. Since it’s not specified ip unnumbered should have been used instead.

- Task 9.1 we are asked to disable proxy-arp and CDP on G0/0 on R6. The solution guide does not disable CDP and only disable proxy-arp.

- Task 9.2 the solution guide have an inbound ACL that permits RIP and BGP but R2 and BB2 does not run RIP or BGP. It does not permit OSPF that is being run between R2 and BB2 and therefore breaks connectivity.

- Task 10.3 we are told that the network administrator has decided to use FTP to backup the routers configuration files and that we should configure R3 to meet the requirements. But in the solution guide no backup solution (like with archive or a kron job) is being configured.

- Task 10.4 we are told to log to the sys10 facility but the solution guide does not do that.
